On June 5, 2014, the U.S. Department of Agriculture issued a federal order that requires producers, veterinarians and diagnostic laboratories to report herds that are positive with swine enteric coronavirus diseases (SECD), specifically porcine epidemic diarrhea virus (PEDv) and porcine deltacoronavirus (PDCoV). Please use the case definitions below to determine reportability of cases:
- Suspect herd: A swine herd in which one or more age groups are affected with acute, contagious, watery diarrhea.
- Presumptive positive herd: A swine herd with one or more positive pigs, tested by PCR, VI, and/or viral genetic sequencing, with either nonspecific, unknown or no clinical signs or history consistent with SECD.
- Confirmed positive herd: A swine herd with one or more confirmed positive cases, that include pigs that:
- Tested positive for PEDV, PDCoV, or other emerging swine enteric coronavirus by PCR, VI and/or viral genetic sequencing; and
- Have a history of clinical signs consistent with SECD.
The federal order also requires producers to work with a veterinarian to develop and follow a herd management plan to minimize the spread and impact of the disease.
Porcine epidemic diarrhea virus does not affect people and is not a food safety concern.

History of PEDv in the U.S.
Porcine epidemic diarrhea virus (PEDv) was discovered in the U.S. in April 2013. At the onset, symptoms including severe diarrhea and vomiting in young pigs led farmers and veterinarians to believe the disease was Transmissible Gastroenteritis (TGE), a disease commonly found in pigs in the U.S. It was soon evident that this disease was something different, causing more significant death loss in piglets. First identified in Europe in the 1970s, PEDv has become common in Asia and has also been confirmed in Canada. How the disease entered the U.S. swine population is unknown.
